Allied to our native P. quadrifolia, but an all round better garden plant, being stouter and more vigorous and having wider leaves in whorls of 7 to 11 leaflets, centred by larger yellow-green flowers on stalks above the leaves. Slow to establish, but with gently creeping rhizomes, this is best in woodsy humus rich soil in shade. From the Caucasus, Armenia and Turkey; I've seen this in relatively high altitude woodland in SW Georgia, under Fagus orientalis, Acer sosnowskyi and Abies nordmanniana.
